ATTACHMENT-HOLDING DEVICE FOR USE ON SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 326,302, datedSeptember 15, 1885.

Application filed June 25,1885. (N0 model.)

To all whom it may concern:

Be it known that I, J osnrrr P. LAVIGNE, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a newAttachment-Holding Device for use on Sewing-- Machines; and I do herebydeclare thefollowing, when taken in connection with accompa nyingdrawings and the letters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawingsconstitute part of this specification, and represent, in

Figure 1, a side view of the presser-foot arranged for ordinary sewing;Fig. 2, a partial section of the presser-foot, showing the at tachmentapplied; Fig. 3, an under side view of the presser-foot and attachmentapplied, the presser-foot turned to one side for the introduction orremoval of the attachment; Fig. 4, the arm of the attachment and fingerdetached, showing the construction to engage with the recess between thepresser-foot and socket.

This invent-i011 relates to that class of attachments which are adaptedto be securedin rear of the presser-foot of the sewing-machine, aud sothat the work passes from the attachment directly beneath thepresser-foot.

In many cases the presser-foot is formed as a part of the attachment,and so that the general presser-foot of the machine is required to beremoved to apply the attachment.

The object of my invention is to adapt this class of attachments to besecured by means of the presser-foot in use on the machine for ordinarywork; and it consistsin the construc tion as hereinafter described, andparticularly recited in the claims.

In illustrating my invention I show a convertible presser-foot-that isto say, apresserfoot arranged so that in one position it may serve forordinary workthatis, as a common presser-foot, but turned to the otherposition will present a hemmer into position for worka well-knownconstruction; and in the illustration A represents the socket-piece,which is attached to the presser-foot bar; B, the presser-footproper,which is formed as a part of a body, 0, standing at an angle tothe presserfoot, the other end terminating in a hemmer or like device,D, the said presser-foot B and attachment.

device D being at the same angle to the body 0, as seen in Figs. 1 and2.

The socket-piece A is constructed with an inclined under facecorresponding to the required incline for the body 0 of the presserfoot,and through the body 0 is a longitudinal slot, a, through which asuitable screw, 1), is introduced into the socket-piece to hold the bodyup to its place on thesocket-piece. On the upper face of the foot is acentral recess, d, and on the under side of the socket-piece is acorresponding projection, 6, adapted to enter the recess (1 in the footwhen turned to its proper position, and so as to prevent transversemovement of the foot. When at work, the slot at permits longitudinalmovement of the body 0, to permit the recess (1 to pass onto or awayfrom the said projection e, and when separated the presser-foot may beturned to bring the hemmer or device D into its place, so that eitherthe presser foot B or device D may be employed as occasion may require.So far this is a common and well-known construction, and the convertiblepresser-foot does not constitute an essential feature of my invention.

Upon the inclined face of the socket-piece a transverse recess, f, isformed to receive the As represented in the drawings, the attachment isa hemmer, E, from which an arm,F,eXtends, and at its end the armisturned at right angles to form afinger, G, correspond ing in width andthickness to the recess f upon theinclined surface of the socket-piece.When it is required to apply the attachment or hemmer E, thepresser-foot proper is turned to one side, as seen in Fig. 3, and so asto expose the recess f. Into this recess the finger G is set, as seen inFig. 3, and then the presser-foot is returned to place, as seen in Fig.2, and in broken lines, Fig. 3, the bodyO of thepresserfoot passing overthe finger which lies in the recess, and so as to secure it therein andhold it in its proper position with relation to the presser-foot.

To prevent possible transverse movement of the attachment, the finger Gis constructed with a recess, it, (see Fig. 4,) on one side,corresponding to the width of theinclined surface of the socket-piece,and so as to interlock therewith, as seen in Fig. 3, or any suitablelocking device may be formed between the socket-piece and finger toprevent such transverse movement.

Vhen the attachment is thus applied, the work proceeds in the usualmanner, passing through the attachment, thence beneath the presser-foot,the attachment always maintaining its proper relation to thepresser-foot and needle.

The presser-foot need not necessarily be a convertible foot-that is tosay, the inclined body may only extend so far up the inclined surface asto make its attachment thereto, and permit it to be turned to one sidefor the introduction of the attachment on the inclined surface, andbetween that inclined surface and the body of the presser-foot.

It will be understood that the recess may be made in the body of thepresser-foot instead of in the socket-piece, as indicated in brokenlines, Fig. 1, it only being essential that there shall be a transverserecess between the surface of the socket and the corresponding surfaceof the presser-foot, so as to inclose the finger which extendstransversely from the arm of the attachment.

I claim- 1. The combination of the socket-piece A, the presser-foot B,constructed with a body, 0, pivoted to the socket-piece, and so as toturn therefrom to the right or left, the attachment piece constructedwith arecess between them adapted to receive the said transverse fingerand thereby support the attachment, substantially as described.

2. The combination of the socket-piece A, constructed with an inclinedunder face, the presser-foot B, constructed with a *gdy, C, inclined tothe presser-foot correspo ing to the inclined surface of thesocket-piece, the said body constructed with a slot, a, a pivotconnecting said presser-foot through said slot with said socket-piece,the presser-foot also constructed with a recess, d, upon its upper face,and the socket-piece with a corresponding downward projection, e, thesocket-piece and body of the presser-foot constructed with a transverserecess, f, between them, the attachment to be applied constructed withan arm, F, and withatransverse finger, G, adapted to be set into therecess between the body of the presser-foot and socket-piece, the saidrecess and finger constructed to interlock one with the other,substantially as described.
